Name to describe people with a typically bitchy, annoying, slap-you-in-your-fat-fuck-face personality. Common amongst individuals with the name "Michael," which may be due to the fact that over two percent of Americans have been presented with that name by their parents.

Fat-Ass Magentas usually talk nonstop about the most retarded crap. They do not leave you alone, disregard personal space, rarely shower, have relatively gross facial features, and are indeed fat. The term, Fat-Ass Magenta, can be used as an insult, although primarily used to express hard feelings or hate toward someone. In the long run, Fat-Ass Magentas only need a decent amount of patience, tolerance, and the ability to see from both perspectives, in order to find the best in the person.

A casual invitation / threat used by an individual that is not afraid of fucking someone up.
